Specification of Letters Patent.

Application filed January 29, 1921. Serial No. 440,956.

To all whom it may concern.

Be it known that I, RUBIN ROSENTHAL, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York have invented a new and Improved Ring-Setting, of which the following is a full, clealgvand exact description.

This invention relates to jewelry and particularly to an improved ring setting and has for an object to provide a construction wherein a stone or jewel of any kind may be readily secured in place without danger ot injuring the same.

Another object in view is to provide a setting in which a seat is permanently connected with the prongs of the ring and arranged to receive the stone or other jewel, the same co-aoting with a clamping ring conforming in appearance with the exposed surface of the stone while presenting an edge over which the prongs of the ring may be bent in the usual manner.

A still further object of the invention is to provide a ring setting in which a seat is provided for a stone and a clamping ring is threaded thereto, the ring being provided with an edge over which the retaining prongs may be bent.

In the accompanying drawing Figure 1 is a side View of the complete ring disclosing one embodiment of the invention.

Fig. 2 is a. top plan view of the structure shown in Fig. 1.

Fig. 3 is a sectional view through Fig. 2 on line 33-, the same being on an enlarged scale.

Fig. 4c is a sectional view through Fig. 3 approximately on line 4.4.

Fig. 5 is a sectional view similar to Fig. 8 but disclosing a slight modified construction to that illustrated in Fig. 3.

Fig. 6 is a sectional view through Fig. 5 on line 6-6.

Fig. 7 is a view similar to Fig. 5 but disclosing a further modified form of the in vention.

Fig. 8 is a sectional view through Fig. 7 approximately on line 88.

Fig. 9 is a view similar to Fig. 7 but showing a further modified form of the inven tion.

Fig. 10 is a sectional view through Fig. 9 approximately on line 10-10.

Referring to the accompanying drawing by numeral, 1 indicates a ring body provided with the usual prongs 2 which may be used for receiving a stone directly but which in the accompanying drawings are designed to receive a clamping ring 3, said ring preferably having its upper face provided with facets conforming with the general appearance of the stone 4-. This stone may be a diamond or any kind of a cut or polished stone but must be formed with some over hanging ed e similar to edge 5 so as to rest upon a seat 6, which seat is preferably annular and also preferably continuous. This seat is supported by anumber of bars 7 connected at 8, said bars being soldered or otherwise rigidly securee to the respective prongs 2 adjacent their upper ends. This forms a rigid but open support for the seat 6, which seat is an annular member.

By providing a seat of this kind the stone 4: is supported for its entire periphery and is then clamped rigidly against its support by the clamping ring 3, which clamping ring as shown in Figs. 1 and 3 is held in place by having the upper ends of the prongs 2 bent over in the usual manner of clamping a stone in place. It will be noted that the prongs 2 are bent over against a metal ring positioned against the stone so that there is no chance of chipping the stone even though the stone may be comparatively easy to chip. Also, by providing facets on the ring 3 corresponding more or less to the facets on the stone the stone will in some circumstances appear to be larger than it really is and thereby present an improved appearance.

In Figs. 5 and 6 will be seen a modified form of the invention in which the bars 7 having an. annular member 9 connected therewith acting as a seat for the stone 4,

said annular member being preferably slotted from the top downwardly with a number of slots 10, while on the periphery threads 11 are provided which permit the clamping ring 3 to be screwed thereon, said clamping ring being provided with some in ternal threads. After theclamping ring 3 has been screwed into position the ends of the prongs 2 may be bent over in the usual manner for preventing any loosening of the rim 3.

fir the construction shown in Fig. 3 the clamping action of ring 3 against the stone is produced by the pressure of the bent over ends of prongs 2 while in Fig. 5 pressure on the stone is produced by the threads ll and the corresponding threads on the clamping rin 1 h Figs. 7 and 8 a further modified form of the invention is shown in which the bars 7 are arranged as shown in Fig. 3 except that the lower ends are cut on including the center section 8. An exteriorly threaded stone seat 12 is connected with the bars 7' and is provided with slots 13 while the clamping ring 3 is provided-with threads 1% engaging the threads 15 of the seat whereby the stone a may be readily clamped in place as tightly as desired before the ends of the prongs 2 are bent over. It will be observed that the bottom 16 of the seating 'member12 is open by reason of the cutting -18 to the position shown in Fig.7 9 and then pressing out the seat prongs 17'to the position shown in Fig. 9. V

What I claim is 1. A ring setting comprising a plurality of prongs, a plurality of bars connected of prongs a with said prongs, a stone seat carried by said bars adapted to-receive a stone and a clamping ring engaging the stone on said seat for clamping the same against the seat.

2. A ring setting comprising'a plurality stone seat connected with said prongs and provided with threads on the exterior face thereof, a clamping ring having an overhanging shoulder and a threaded a section, saidthreaded section being adapted to screw onto the threads of said seat while the overhanging shoulder clamps the stone against said seat, sa1d clamp1ng ring being formed on its periphery so that the ends of said prongs maybe bent thereover.

3. A ring setting comprising a plurality of" prongs, a plurality of bars connected with said prongs adjacent the upper ends, SiLlCl bars extend-mg diagonally toward the base of the prongs and connected together by a central integral plate, a stone seat con nected with said bars and extending upwardly therebetween, the various parts or" said seat forming substantially an annular support and a clamping ring having an overhanging shoulder adapted to press a stone against said seat, said clamping ring being formed with an outer face and peripheral edge having facets thereon whereby the ends of said prongs may be bent over said edge.

1. A ring setting comprising a plurality oi prongs adapted to be connected with a ring, means for supporting a stone in said prongs and a clamping ring for holding said stone in place, said supporting means comprising an inserted member formed from a single piece and pressed out so as to present a supporting bar for each of said prongs to which they are connected and an upstanding section arranged between each of said bars adapted to receive said stone, said clamping ring being formed to hold said stone on said supporting members while said prongs are adaptedto be bent over to the clamping ring for holding the same in place. g

5. A ring setting comprising a plurality of prongs, a plurality of bars connected with said prongs adjacent thecupper ends,

said bars extending diagonally towardthe.

base of the prongs and connected together by a central integral plate, a stone seat conneat-ed with saidbars, said stone seat being gsubstant1ally annular and a clamping ring having an overhanging shoulder adapted to press a stone against said seat said ring being formed with an outer face and peripheral edge with the contour of facets whereby the ends or" said prongs may be bent over said edge.

6. A ring. setting comprising-a plurality of prongs, a plurality of bars connected with said prongs near the upper end and 6X-' tending at an angle downwardly, a member acting as a stone seat secured to said bars, said member being substantially in -the form of a ring open at the top and bottom and threaded exteriorly,- a clamping ring having an internally threaded sectlon and'an overhanging shoulder, said threaded section being adapted to be screwed onto {the threads of said seat while the shoulder engages the stone and forces the same against said seat, said clamping ring being formed with an edge capable of permitting said prongs to have their upper ends bent thereover whereby the clamping ring is locked against accidental removal] RUBIN nosn TI-IAL;
